Joule Thief

[guruji]

I'm not really sure if this should be posted here or in Dr Stiffler's thread.

I'm using a cell phone charger to run a joule thief thats running a SEC 15.
It's also charging a 12v 7.5 ah battery and ten AA batteries and making light at the same time.

Here is a video of it.

Hi Slayer007 nice setup you've got. Can you please post a schematic of that circuit?
Thanks

There is a led in the basic jt spot and a bulb on the secondary.

And it light brighter then on the battery only.

I tried diamagnetic, paramagnetic, and ferromagnetic materials for secondary .

Even combination of diamagnetic and paramagnetic since they react in opposition.

I also hung a roll of garden wire over it and got a led to light on it.\

More test needs to be conducted with ferromagnetic , those are planed today.

I made a compass trial , it moves the needle counter clockwise about 10 degree every time i put the battery on , if i pulse it it rotated . it needs to be slower then my jt can.

It is in the audio range i may try something with my guitar to find sweet spots .

1khz is a B on the third string , i have to build a square wave oscillator also i think i will make it from a op amp that is all i have , for now . Plus it need i bit more than 1.5v , so i may have to go to a 9v.

I also found this square wave at 1.5v , 2 transistor.
